Thanks for reply. What I want to achieve? - build an FB to handle ASi I/O functions, r/w, query status (LPS, LDS) - input (I/O read) data's pass to a DB, out data's come also from a DB - FB will be universal (handle more ASi Master(s) w. independent DB's) Whats wrong? - access I/O area [IB272... in my case] with indirect addressing in SCL. In STL the base functions (access A/B area, LDS, LPS access w. ASI3422) working well, as in manual of CP343-2. I try to use LAD and SCL in this project. The naked issue: why can't work in my casehdhosseini's code(as suggested) inside FB: [code]#test := IW(#hd):P;[/code] When I migrate my original (v5.5) project.s7p sample, I get result in generated SCL as original thread starter,Mr Lindhsaid: [code]#PIW_indirect:=IW(#Addr):P;[/code] After migrating, looks like OK, no error while compiling - but ASi read always give back zero's. Therefore I try to write a few line's SCL to clarify, IB(#l_Addr):P, why can't give back I/O data. Thanks
